Moreover, the content of the standard has been brought in line with the revised ISO 898-2. This standard is identical to the European Standard EN ISO 7719:2012 in which the International Standard ISO 7719:2012 was adopted without any modifications. This standard has been prepared by ISO/TC 2 "Fasteners" in collaboration with CEN/TC 185 "Fasteners", both secretariats of which are held by DIN. The responsible German standardization committee is Working Committee NA 067-00-03 AA "Verbindungselemente mit metrischem Innengewinde" ("Fasteners with metric internal thread") of the Standards Committee Fasteners (FMV) at DIN.
